SAN FRANCISCO—Analog IC startup Touchstone Semiconductor Inc. Wednesday (Aug. 31) introduced an analog comparator billed as a drop-in replacement for Maxim Integrated Products Inc.'s MAX917 comparator.
The TSM917 is suited for low-voltage, power-sensitive applications for portable products, such as two-cell battery monitoring/management, according to Touchstone (Milpitas, Calif.).
The introduction of a drop-in replacement for a Maxim part ties into Touchstone's strategy to serve as a second source for commonly used, high-performance analog parts. The company came out of stealth mode in June to announce its strategy and disclose the receipt of $12 million in series A venture capital funding.
Touchstone said Wednesday that electronics manufacturers can use both the MAX917 and the TSM917 interchangeably to ensure that product manufacturing is not delayed by part unavailability. Free samples are available upon request, Touchstone said.
The low-power, single-supply TSM917 is pin-compatible and specification- and functionally identical to the MAX917, Touchstone said. It operates from a single +1.8V supply, incorporates an internal 1.245V ±1.5% voltage reference, and consumes no more than 750nA of supply current, the company said. The TSM917 is in stock and production quantities are available to ship immediately, the company said.
The TSM917 is offered in space-saving 5-pin SOT23 and 8-pin SOIC packages, Touchstone said. Prices start at 95 cents each in 1,000 piece quantities and can be ordered from Future Electronic, Touchstone said.
